Agroup of particles is traveling in a magnetic field of unknown magnitude and direction. you observe that a proton moving at 1.30 km/s in the +x-direction experiences a force of 2.10×10−16 n in the +y-direction, and an electron moving at 4.20 km/s in the −z-direction experiences a force of 8.20×10−16 n in the +y-direction.
a. what is the magnitude of the magnetic field?
b. what is the direction of the magnetic field? (in the xz-plane)
c. what is the magnitude of the magnetic force on an electron moving in the -y-direction at 3.70km/s ?
d. what is the direction of this the magnetic force? (in the xz-plane)

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
